Davis Solar Radiation Sensor w/3' Cable

Required to monitor evapotranspiration. Diffuser element and housing are carefully designed for accurate cosine response. Silicon photo diode provides good match to solar spectrum. Two-piece housing minimizes radiation heating, allows convection cooling of the sensor, and prevents the trapping of water or dust. Includes built-in level and 3' cable. Can be used with the cabled or wireless Vantage Pro® Weather Stations.
